2025 F1600 Championship Series

The 2025 F1600 Championship Series season was the fourteenth season of the F1600 Championship Series.

The prior year's winner was Mateo Naranjo from Team Pelfrey.

The 2025 F1600 Championship had the tightest title race to date as Ayrton Cahan narrowly surpassed his brother and teammate, Gabriel Cahan, and Wesley Gundler by only 2 points.

David Adorno dominated the F1600 Masters class to claim the season title; his fifth-place finish in the general standings marked the highest rank for a Masters competitor in over ten years.

Scoring system

Points are awarded to the top twenty-five classified drivers, and the top drivers who are able to achieve the Pole Position or the Fastest Lap during the qualify session are awarded with corresponding +3 and +2 bonus points.

The Season Championship will recognize only each driver's best 18 of 21 race results including all bonus points earned.

Points are awarded using the following system:

Position 1st  2nd  3rd  4th  5th  6th  7th  8th  9th  10th  11th  12th  13th  14th  15th  16th  17th  18th  19th  20th  21st  22nd  23rd  24th  25th+  DNF Points504237343129272523211917151311109876543211

Guest drivers are ineligible to score points.

If a guest driver finishes in first position, the second-placed finisher will receive 50 points. The same goes for every other points scoring position. Thus, if three guest drivers place fourth, fifth and sixth, the seventh-placed finisher will receive 34 points and so forth – until the twenty-eighth-placed finisher receives the final point.
